ATENT PAPER-MAKING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 726,980, dated May 5,1903.

Application filed June 16, 1902. Serial No. 111,809. (No model.)

To ctZZ whom it may concern.-

Be it known that LANDREW OUTERSON, a

citizen of the United States of America, re-

siding at -Windsor Looks, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inPaper-Making Machinery, of which the following is a specification. s

The object of this invention isto provide a machine which will produce apaper which shall be free from the markings caused by the wire on whichthe paper is made.

My invention has particular reference to paper made on Fourdriniermachines and does not concern itself with paper 'made by otherprocesses. 7

Another advantage resulting from my invention is the combination withthis machine of means for making what is known as a deckle-edged paper.

Figure 1 is a perspective view of'part of a machine in which myinvention is'embodied. Fig. 2 is a diagrammatic View showing thedelivery ends of the machines andthe devices between them.

In carrying out my invention Imake use of two Fourdrinier machines. Theoperation of these Fourdrinier machines is well known to those familiarwith this art, the pulp being flooded onto the wire at one end, which issometimes called the making end of the machine, and as it travels towardthe other end of the machine it is felted and dried, so that it is takenofi at what is called the delivery end of the machine in a-continuoussheet. I arrange these machines with.

B denotes the sheet of pulp formed on the Wire 1). The wires travel inthe direction indicated by the arrows, the roll 2 being the delivery endof the machine A and the roll 3 be-. ing the delivery end of the machineB. Each arrows. the pulp on the wire it picks it off from the machine isprovided with the ordinary couchrolls 5 6. Y

The machine A is provided with the ordinary felt C, which passes oversuitable idlerrolls and between the roll 2 and the couchroll 5, thenbetween the couch-roll 5 and the pressure-roll 7, back in the directionof the As the felt C comes in contact with wire and carries it aroundthe couch-roll 5 and between it and the pressure-roll 7. Betweenthedelivery ends of the machines I position a conveyor of any kind, as ashort endless belt D, which travels about the rolls 8 9. This shortendless belt takes the pulp from the wire I) after it has passed betweenE,which dampens the wire sides of the sheets 1 before they are joinedand insures a more perfect union.

As above stated, I provide in connection with this machine means forcutting one of the sheets of pulp, as B, into strips with deckle edges.This is'done by arranging the jets 100 so that they will be projectedupon the sheet just before it is couched by the rolls 3 6. In makingpaper for special usesas, for instance, envelopsit is sometimesdesirable to reinforce certain parts of the fsheet'as, for instance, theparts which make up the front or back of the envelop. To do this, onlythe alternate strips which are formed by the jets 100 are carried up bythe felt D, the others being carried around the roll 3 and back into thepulp-chest. In other respects the machine operates exactly as abovedescribed.

I claim as my invention- 1. In a machine of the class specified, incombination, the two Fourdrinier machines arrangedwith their deliveryends opposite one another, a felt for one of said machines, and anendless belt or conveyer arranged between the ends of the two machinesas and for the purposes specified.

2. In a machine of the class specified, in combination, the twoFourdrinier machines arranged with their delivery ends opposite oneanother, a felt for one of said machines,

passing about the couch-r011, a pressure-roll cooperating with theconch-roll, and an endless belt or conveyer located between the deliveryends of the two machines, as and for the purposes specified.

3. In a machine of the class specified, in combination, the twoFourdrinier machines arranged with their delivery ends opposite ANDREWOUTERSON.
